TLE5028C

iGMR-based speed sensor

TLE5028C is our 2nd generation Crank speed sensor solution based on Giant Magneto

Resistive (iGMR) technology. It provides a higher air-gap and greatly reduced jitter over

frequency and temperature performance. All of which puts it ahead of other magnetic

sensing technologies and makes it the preferred solution for high-accuracy powertrain

speed sensor systems – both today and in the future. TLE5028C can detect the rotation

direction of a wheel and transmits this information during the first output pulse, making

it the perfect fit for the latest engine systems that use a start-stop feature as well as for

automatic transmission applications in the automotive sector. It´s improved robustness

against ESD and EMC answers to the challenges of harsh high power environments typically

present in hybrid systems. TLE5028C is available in our well-established, module-style

package with integrated capacitors. It uses a three-wire digital voltage interface (PWM).

TLE4988C

Reduced dependence on rare-earth backbias magnets thanks to advanced performance

The Infineon XENSIV™ TLE4988C products feature advanced camshaft sensing performance and

improved application adaption. One major benefit of the advanced sensor performance is the re-

duced dependence from rare-earth backbias magnets for module manufacturers. The TLE4988C

has proven right performance with a ferrite backbias magnet for all relevant parameters such as

phase jitter, phase accuracy or speed effect across key temperature, air gap and rpm ranges.

Features

› Digital output signal (voltage interface)

› True Power On functionality (TPO)

› Auto TPO – automatic in car calibration

› Improved switching level/phase accuracy

› TC range including ferrite

› High speed digital interface for diagnosis / test

› Twisted Independent Mounting (TIM)

› EEPROM for algorithm options and ID (on request)

› Increased ESD and EMC immunity, improved µCut feature

› Digital magnet temperature compensation

› Mechanical stress compensation

› Module package PG-SSO-3-5

Applications

› Camshaft speed and position
